Webconcrete’s strengths will depend on many factors (water/cement ratio, type of agragets, cement amont/m3, .. strength additives such as slag, ..etc) The stregth are normally designed by materials engineer just like any other engineering design: can go up or down by adjusting the parameters. You should aslo control your yield to be within the range.
